Executive Summary

This vulnerability affects openssl_encrypt versions before 1.4.0. It allows attackers to bypass sandbox restrictions in the default process isolation mode, enabling malicious plugins to execute with full access to the filesystem, network, subprocess execution, and all Python modules.

Detection Guidance

Check the version of openssl_encrypt installed on your system. If it is below 1.4.0, the system is vulnerable. Run: pip show openssl_encrypt or pip list | grep openssl_encrypt to verify the version.

Impact Analysis

Attackers could exploit this to run unauthorized code, steal sensitive data, install malware, or disrupt systems by gaining unrestricted access to system resources and functions.

Compliance Impact

This vulnerability could lead to data breaches, unauthorized access, or data exfiltration, violating GDPR and HIPAA requirements for data protection and access controls.

Mitigation Strategies

Upgrade openssl_encrypt to version 1.4.0 or later immediately. If upgrading is not possible, disable plugin execution in process isolation mode or switch to threading mode which enforces sandbox restrictions.
